STAGE ONE INSTRUCTIONS
1. Remove the vacuum slide from the carb. Remove the stock needles
and spacers, noting order of assembly (Fig. A). Using the drill bit
provided (DD #30) enlarge your slide lift hole. The picture may not show
your slide exactly. Drill only the existing slide lift hole, do not drill the
needle hole or any new holes.
2. Install the Dynojet needles on groove #2 from the top. Install the
small Dynojet washers above the e-clip. After installing the slides in the
carbs be sure to check slide movement manually.
3. Remove the stock main jets and replace with the Dynojet main jets
provided. If you are running the stock exhaust install the DJ078 main
jets. If you are running an aftermarket exhaust or slip-on with high
flowing baffle use the DJ082 main jets. Be sure that the jet you are
changing is the main jet.
4. Locate the fuel mixture plug (Fig. B). If you see a screw head at
Fig.B then proceed to the adjusting procedure. With the 5/32 drill bit
provided carefully drill through the plug. NOTE: The mixture screw is
directly underneath this plug, be ready to pull back on the drill the instant
you break through. Use screw provided to secure and remove this plug.
Carefully turn the mixture screw clockwise until lightly seated, then back
out 2.5 turns.
